Maybe you're someone to ask. Why don't we have sweet apartment buildings like the kind you find Tokyo? In the heart of Tokyo you can rent a tiny (but complete, clean, modern, beautiful) apartment for < $1k. In most major US cities that's totally impossible.

They're small as hell, but totally sufficient and way nicer than living in a bigger shittier place.

I think someone could make a killing bringing these kinds of buildings to the US.

Any reason it's not possible?
